 GENERAL

This document describes the system configurations, development/maintenance, software configurations, network and specifications, for two types of autonomous controllers in the STARDOM: FCN with NFCP100 CPU module and FCJ.  (FCN is an acronym for field control node, and FCJ for field control junction.) Notation in this document: 

 • The term “FCN” refers to the module consisting type autonomous controllers.

 • The term “FCN-500” refers to the autonomous controllers with NFCP501/NFCP502 CPU module. 

 • The term “FCN-100” refers to the autonomous controllers with NFCP100 CPU module.

 • The term “FCN-RTU” refers to the low power autonomous controllers with NFCP050 CPU module.

 • The term “FCJ” refers to the all-in-one type autonomous controllers.

l FCN-100

l FCJ

FCJ is an all-in-one controller with a built-in I/O interface — ideal for installing inside machine equipment as well as configuring a distributed system. Its control network can be duplexed. For hardware details, refer to FCJ Autonomous Controller Hardware, GS 34P02Q11-01E

 FEATURES

l High Performance

• Applicable to a variety of processes, from sequence control processes to analog control processes. 

• Intercommunication with other autonomous controllers or other equipment for inter-linked control actions, in addition to stand-alone operation. 

• Using Versatile Data Server Software (VDS) or Supervisory Systems (FAST/TOOLS) together allows a system with enriched operation and monitoring functions to be built up. • An FCN/FCJ OPC server for Windows can be used for accessing the data of an FCN/FCJ from an OPC (OLE for Process Control) client on a PC. 

• Java-enabled — enables users to implement various applications, including displaying images on a Web browser, saving data files, transferring files using the FTP protocol, sending/receiving e-mails and public network connection using the PPP protocol. With InfoWell, applications such as web browsers and e-mail communications can be utilized without programming.

l High Reliability

• RAS features (CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more) 

• Memory with error-correcting code (ECC) 

• Low heat dissipation, eliminating the need for a cooling fan 

• The Ethernet control network, CPU, power supply module, and SB bus (FCN local bus) can all be duplexed for an FCN-100. 

• The control network can be duplexed for an FCJ.

l Engineering Efficiency

• Five IEC 61131-3 compliant programming languages are supported, enabling the user to selectively use these languages according to their purposes of use and applications. 

• Control logic can be encapsulated into software parts for reuse, allowing efficient and quality system configuration.

• Application Portfolios packed with Yokogawa’s application expertise, enable easy implementation of advanced functions, including control-loop instrument blocks and communication with non-Yokogawa PLCs.

l Easy Maintenance

• Online download function allows a control application to be modified during system operation 

• All modules are hot-swappable with an FCN-100.

 CONFIGURATIONS

l System Configurations Both FCN and FCJ are locally mounted controllers to allow diverse systems to be configured according to the individual users’ work sites; however, the possible system configurations can be broadly divided into three types:

 • A system consisting of a standalone FCN or FCJ 

 • A system in which FCNs and/or FCJs are connected to each other through the control network and perform interlinked actions (up to a total of 15 FCNs and FCJs can intercommunicate with one FCN/FCJ).

 • A system in which one or more FCNs and/or FCJs are interlinked with VDS, FCN/FCJ OPC Server or FAST/TOOLS (up to a total of 4 VDSs, FCN/FCJ OPC Servers and FAST/TOOLS can be connected).

l Development and Maintenance of FCN/FCJ

A PC/AT-compatible computer is used for development and maintenance of applications for an FCN and FCJ. Resource Configurator is a tool program to be installed in the computer used for maintenance, and is used to make the FCN/FCJ hardware settings. The user can access FCN and FCJs via a Web browser from a PC to make detailed settings for the network and so on, and to perform maintenance operations such as database backup and restoration. Logic Designer is a tool program for the development of control applications for an FCN/FCJ. Logic Designer requires a license to run. These tool programs are supplied on a DVD-ROM.

The data is retained even if the power is off. The data is retained during a power failure (can be used to store tuning parameter settings for the control application). Retained Data Area for control application is Max 350 KByte.

l Network (Ethernet) Specifications

Application Ethernet is used as the control network, which can be dual redundant, connecting FCNs/FCJs with various PLCs, display units and VDS. FCNs/FCJs are developed and maintained via Ethernet as well.

l Network (Serial) Specifications Serial ports can be used to link diverse devices and controllers.

Communication portfolios facilitating interconnection with display units, various programmable logic controllers, temperature controllers, and power monitors are available via a serial port.

l Guideline of Control Application Capacity

a total of the following. (1) Function blocks (POUs) Up to 512 

 • Regulator control blocks (e.g., indicator blocks, controller blocks, and manual loaders): Up to 128

 • Others (e.g., calculation blocks, switch instrument blocks, and communication POUs): Up to 384 (2) Sequence program Up to 180 kilosteps in Ladder or up to 128 sequence tables each of which has 32 condition and 32 action rows. Example of a control application with the maximum size:

 • Inputs/outputs: 96 AIs, 32 AOs, 256 DIs, and 256 DOs 

 • PID loops: 32 

 • Sequence program: 128 sequence tables 

 • Control cycle: 1 second

l Specification of FCN-100 with Duplexed CPU Modules 

 • After a failure of the CPU in service, the stand-by CPU obtains the control right instantaneously and resumes control without any influence of the CPU switchover. • When additionally installing a CPU module to an FCN with a single CPU module to configure duplexed CPU modules, such as when replacing a failed CPU module, carry out the All-program-copy (APC) command for equalization between the CPU modules. It is also possible to run the APC command automatically after CPU replacement. When the APC command is running, the control period lengthens by a second or two only during its first cycle. (1) 

 • Synchronization is periodically performed between the in-service CPU and stand-by CPU. The total processing time is hence longer than that of an FCN 100 with single CPU. • If the control application comprises multiple tasks, those tasks cannot access the same global variable.

 • The CPU module’s serial port cannot be used. 

 • Java applications cannot be run. 1: If one of the two CPUs in dual-redundant configuration is not style-3 NFCP100 CPUs, the APC command cannot be started automatically. In this case, control stops when the APC command is running and the I/O modules operate in the same way as they do when the Fallback option (can be set to ‘hold the output’ or ‘output specified values,’ for example) is selected. l Online Download Function 

 • Online download function is a feature with which control applications can be modified while a control function continues in operation. • With this feature, I/Os, variables, data types, program codes, and libraries can be added, deleted or modified.

 • Modifying the control loop during system operation does not affect other control loops. Changing a range of control loop or loop connection causes the control loop to become the MAN mode. l Implementation of Java Virtual Machine 

 • WWW server functionality: download HTML files and Java applets to Web browsers and access data in FCN-100s and FCJs 

 • E-mail transmission/reception: send and receive e-mail using SMTP and POP3 protocols, respectively support the authentication function of SMTP servers (SMTP Authentication/Pop Before SMTP) 

 • FTP client/server functionality: transfer files to/from other networking systems 

 • PPP (Point to Point Protocol) functionality: exchange data with a PC or a cellular phone via the public network such as GPRS by connecting a modem to a serial port of FCN/FCJ support the client mode and the server mode unsupport FCN-100’s serial port on one of duplexed CPU modules.

l Time Synchronization Function FCNs/FCJs enable time synchronization among equipment supporting SNTP (Simple Network Time Protocol). An FCN/FCJ can operate as an SNTP server or as an SNTP client.

l Connection to Display Unit FCNs and FCJs can connect a display unit using FA M3 Emulation Function or Modbus Communication Portfolio.
